Also I feel like 5th to 6th was a bigger jump forward than 4th to 5th. Like, yeah, the sudden ability to have 3D graphics was amazing at the time but it also felt like a step back in a lot of ways - even at the time I knew that the SNES/Genesis games of the time looked sharper visually and were more polished. The difference between 5th to 6th on the other hand is wild - PSX/N64 games feel noticeably like they're from a totally different time and place but PS2/GC/Xbox can almost pass itself off as current. That was really the last generation where I felt like, holy shit, we're in the future. After that it's been creeping incremental changes.
